Product Introduction

Application field: Mainly used to prevent impurities from adhering to pipes in a molten state, achieving pipe sizing and cooling through vacuum holes on vacuum pipelines.

Testing: the six way crosses correctly switch the fluid flow direction; Performance testing checks whether the performance indicators of the components meet the specified requirements, such as the sizing accuracy and cooling efficiency of the vacuum pipe sizing device

Surface finish: Some applications require a high level of cleanliness, so choose fittings with appropriate surface finishes to minimize particle generation.
